How many skills went into the making of the tint and the kilns, into supplying the heat, the light and power, the belts, motors, and all the other things a mill requires?

制造颜料，烘干需要的热量，照明，电力，传动带，电动机，一家工厂所需要的一切设备，等等，所有这一切需要多少技能？

New types of tiny combined heat and power plants are able to turn about half the energy in fuel into electricity, almost matching the efficiency of huge generators.

新型的小规模热电联产机组，能够将燃料中大约一半的能量转化为电力，其效率已与大型发电机的效率相若。

Scientists think this haze, which is created by power stations and cooking-fires, may be radiating heat into the lower troposphere, at altitudes in which glaciers are found.

科学家认为这种云雾由发电站以及烹饪生火等形成，可能像低对流层辐射热量，而冰川却正好位于这个位置上。

By 2015 or so, the average silicon chip will consume about 150 watts of electrical power, turning this into heat a thought which is already taxing the minds of some engineers.

The vehicle is powered by what is essentially a nuclear battery that converts heat into electricity providing power to Curiosity's instruments as well as generating warmth during the frigid Martian nights.

IMechE says this process is only 25% efficient but it is massively improved by co-siting the cryo-generator next to an industrial plant or power station producing low-grade heat that is currently vented and being released into the atmosphere.
